MOSCOW, March 23. /TASS/. British diplomats expelled from Russia have left Moscow and are heading for London, a UK diplomatic source in Moscow told TASS.

"They've left Moscow and their jet will land in London soon," he said.

A group of 23 Russian diplomats have been expelled from Russia as a response to British Prime Minister Theresa May's decision to expell 23 Russian diplomats from London in the wake of the alleged poisoning in Salisbury of the former Russian intelligence officer and British spy Sergei Skripal and his daughter Yulia. The British authorities aportioned blame for the incident to Russia without producing any substantiated evidence.
